IMPRESSION OB IMIT'ATION STITCH MACHINE.

Patented Sept. 19, 1911.

Application filed July 18, 1904. Serial N 0. 216,970.

To all whom it may concern:

Be it known that I, JOHN B. HADAWAY, a citizen of the United States,residing at Brockton, in the county of Plymouth and State ofMassachusetts, have invented certain new and useful Improvements inImpression or Imitation Stitch Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

The present invention relates to impression or imitation stitch machineswhich are used in the manufacture of boots and shoes to form ornamentalindentations upon the upper surface of the projecting edge of the sole.

More particularly the present invention relatesto impression orimitation stitch machines which comprise a rotary indenting wheelprovided with teeth so shaped and spaced as to produce the desired formof indentation.

The present invention consists in certain constructions, arrangementsand combinations of parts hereinafter described and claimed, tending tosimplify and improve the construction and operation of machines formaking imitation or impression stitches.

The invention will be clearly understood from an inspection of theaccompanying drawings in which Figure 1 is a view in side elevation ofan impression or imitation stitch machine embodying the same in itspreferred form. Fig. 2 is a view in front elevation of the machineillustrated in Fig. 1. Fig. 3 is a detail view in side elevationillustrating the indenting wheel and a portion of the mechanism foractuating the'same. Fig. 4: is a detail view in front elevation of theparts illustrated in Fig. 3, the indenting wheel shaft and the pinion onthe rear end of the shaft being shown in section. Fig. 5 is a detailview in front elevation of the guard plate which extends in front of theindenting wheel and prevents the wheel from coming in contact with theupper of the shoe being operated upon. Fig. 6 is a plan view of thewheel guard with the guard plate attached thereto, and Fig. 7 is a Viewin front elevation of the wheel guard illustrated in Fig. 6 with theguard plate removed.

1 indicates the work support upon which the tread surface of the sole ofthe shoe being operated upon is supported. As illustrated, this worksupport is frusto-conical in shape and is rotatably" mounted upon a studset in a block 2 pivotally mounted at 3 in the upper end of a slide 1.The block 2 is provided with flanges extending on each side of the upperend of the slide 4:, and one of these flanges is provided with an areshaped slot as illustrated in Fig. 1 through which a securing bolt 5passes. The block 2 can thus be adjusted about its pivot 3 to change theangle of inclination of the surface of the work support in contact withthe shoe so that the shoe can be properly presented to the indentingwheel.

The slide 4: is mounted in a vertical guideway in a bracket 6 secured tothe front portion of the machine frame. From the lower end of the slidea rod 7 projects downwardly through a sleeve 8 having a screw threadedengagement with the lower end of the bracket 6. A spring 9 surrounds therod 8 and is interposed between the lower end of the slide 4 and theupper end of the sleeve 8. The spring normally holds the slide 4 and thework support mounted thereon raised and is sufficiently strong to forcethe work against the indenting wheel so as to cause the teeth of thewheel to indent the work to the desired depth. By adjusting the sleeve 8in the bracket 6 the tension of the spring 9 can be regulated asdesired. l/Vhen there is no work in the machine the upward movement ofthe slide and work support is limited by a stop collar 10 adjustablysecured to the lower end of the rod 7 and arranged to engage the lowerend of'the sleeve 8. A suitable rod or chain (not shown) connects thelower end of the rod 7 with a foot treadle the depression of whichlowers the slide 4 and work support 1 to enable work to be inserted inthe machine. The downward movement of the slide and work supportare'limited by means of an adjustable stop screw 11 mounted in the slide4 and arranged to engage the upper surface of the bracket 6. p g 7 h Theindentingwheel is indicated at 12 and is. rigidly secured upon theforward end of a shaft 13 journaled in the lower end of a lever 14. Theindenting wheel is frustoconical in shape and is located above the worksupport 1 in position to bear upon the upper surface of the edge of ashoe sole supported thereon. The lever 14 is pivotally mountedupon ahorizontal stud 15 project-- ing from the front portion of the machineframe, and is formed at its upper end with two arms between which twosliding blocks 16 are mounted. In theseblocks a'bearing is formed whichis engaged by an eccentric pin 17 on the forward end of a driving shaft18' mounted in bearings in the upper portion of the machine frame. Theshaft 18 is provided with fast and loose belt pulleys 19 and 20 andduring the operation of the machine is rotated constantly by means of abelt passing over the fast pulley. Through the eccentric pin 17 andblocks 16 an oscillating movement is imparted to the lever 14 and theindenting wheel 12 is moved bodily back and forth in the direction ofthe feed. The lower end of the lever 14 moves through a comparativelyshort are so that the indenting wheel is vibrated in substantially ahorizontal plane. Upon the rear end of the shaft 13 upon which theindenting wheel 12 is mounted is rigidly secured a pinion 21 whichmeshes with a worm 22 secured upon a horizontal shaft 23 mounted inbearings in a bracket 24 bolted to the front portion of the machineframe above the bracket 6. To

the outer end of the shaft 23 is secured a skew gear 25 which mesheswith a skew gear 26upon the lower end of a shaft 27 mounted in bearingson the machine frame and arranged at an angle to the vertical. At itsupper end the shaft 27 is provided with a skew gear 28 which meshes witha skew gear 29 secured upon the driving shaft 18. Through the gearingabove described a constant rotation is imparted to the worm 22 duringthe operation of'the machine.

The movements which are imparted to the indenting wheel are produced bythe oscillations of the lever. 14 and the rotation of the worm 22, thepinion 21 upon the indenting wheel shaft 13 remaining constantly in meshwith the worm 22 and being rolled back and forth thereon as the lever 14oscillates andat the same timebeing given a movement of rotation by therotation of the ously through the machine at a uniform rate of speed.The operation of the indenting wheel is precisely the same as if theindenting wheel were mounted to rotate loosely so as to be turned by thecontact of its teeth with the work and were rolled back and forth overthe work while the work was being fed at a uniform rate of speed throughthe machine.

In order to take up wear between the arms of the upper end of the lever14 and the blocks 16 the arms are connected at their upper ends by meansof an adjusting bolt 30 as illustrated in Fig. 2.

It is desirable in machines to which the present invention relates toprovide means for heating the indenting wheel. Accordingly the machineillustrated in the drawings is provided with a gas pipe 31, as indicatedin Fig. 2, which is secured by a clamp to the bracket 24 and is providedwith a jet pipe 32 extending in close proximity to the-indenting-wheelshaft at the rear of the indenting wheel.

In order to protect the operator from injury and also to prevent theindenting wheel from coming in contact with and marring the upper of theshoe being operated upon a guard 33 is provided which is secured to thebracket 24 by means of a bolt 34 as indicated in Fig. 1, so as to beadjustable horizontally. This guard which is illustrated separately inFigs. 6 and 7, is provided with a recess in which the indenting wheel isreceived, the guard extending on both sides and over the top of thewheel. Upon the forward end of the guard 33 a guard plate 35, shownseparately in Fig. 5, is secured, which extends in front of theindenting wheel in a position to bear against the upper of a shoe wheninserted in the machine.

The nature and scope of the invention having been indicated and amachine embodying the preferred form of the invention having beenspecifically described, what is claimed is:

l. A machine for making impression or imitation stitches, having, incombination, a work support, an indenting wheel and mechanism actingautomatically to roll the wheel back and forth over the work and toactuate the wheel to feed the work during its rolling movements,substantially as described.

2. A machine for making impression or imitation stitches, having, incombination, a work support, an indenting wheel and mechanism act-ingautomatically to roll the wheel back and forth over the work and toactuate the wheel to impart a continuous feeding movement to the work,substantially as described.
